Patented Oct. 13, 1931 PATENT OFFICE j PETER J. WESOLOWSKI, F DETROIT,MICHIGAN WINDOW FASTENER Application filed November 26, 1928.

This invention relates to window fasteners and more particularly to acombined fastener and latch construction including means for securingthe window sections in rela- H tively adjusted positions.

The invention has an object to simplify, render more efficient, andimprove generally constructions of this type-and these, as well as otherobjects, advantages, and the novel details'of construction will be mademore apparent as this description proceeds, especially when consideredin connection with the accompanying drawings, wherein Figure 1 is afragmentary perspective view of a windowwith my invention attachedthereto;

Figure 2 "is afvertical' sectional view through the device;

Figure 3 is a sectional elevation taken substantially on thezplaneindicated by line 33 in Figure 2; and

Figure '4 is a fragmentary elevational view of the link and its support.

" Referring now particularlyto the draw- 1 ings wherein like'referencecharacters indicate like parts, it will be-noted that there isillustrated the adjacent rails and 11 of two window sashes preferably ofthe vertical slidabletype which are movable in the man'- Nm nersuggested in Figure 1 for opening the window and assume the positionshown in Figure 2 when-closed. that is with their rails 10 andlladjacen'tone another.

r My improvedwindow fastenerconsists essentiallyof a bracket 12 adaptedto be secured to the rail 10 of one'of the sashes, this bracketconsisting of a base plate 13 and an uprightportion 14: The bracket 12has a dual vfunction of constituting a support for the r connectinglinkor arm 15 and of constituting a keeper plate for thelocking element ofthe fastener. The link or arm 15 is in the form of an elongated platemember provided with a longitudinally extending slot 16, the member 15being also formed with a lateral ear at one end thereofthrough which ispassed a rivet or y stud 17 which also extends through the up rightportion 14 of bracket 12 for pivotally securing link 15 thereto. Theupright por- Serial No. 321,935.

tion 14 of bracket 12 is also provided with a cutaway portion forming akeeeper slot or recess 18. the base 13 of the bracket being alsopreferably cut away as at 19 to facilitate the engaging of the lockingelement yet to be re 58 ferred to. The slot 16 of link member 15 isprovided with an enlargement 16' at the end thereof adjacent its pivotalconnection to the bracket 12.

Mounted on the rail 11 of the other sash section is a complementarylatch or fastener member indicated generally by the reference character20. This member consists essentially of a base 21 and a housing 22. Thebase portion 21 provides means for attaching this fastener member to therail 11, as for instance by means of screws or the like 23. Mounted inthe housing portion 22 and extending therethrough is the shaft 24 of alocking element. One end of shaft 24 is provided with a head having anannular groove 25 and consisting further of an angular crank or arm 26and a laterally bent end or projection 27. The other end of shaft 24 isprovided with cam member 28 adapted for engagement with a cam surface 29formed on the housing 22 and an operating handle 30. Surrounding theshaft 24 and arranged within the housing 22 is spring 31 which bears onthe one hand against a wall of the housing and on the other hand againsta shoulder 32 formed on shaft 24. This spring acts to norrnally projectthe head of the locking member outwardly from the housing 22.

and 11 are thus completely closed and locked against relative movement.Upon rotation of the locking member to disengage the projection 27 fromthe keeper recess 18 the sashes may be relatively moved and thus one ofthem opened a distance corresponding to the length of slot 16 as will beobvious. When one of the sashes has been thus adjusted the sashes may belocked against further relative movement by rotating handle 30 of thelocking element, whereby the arm 26 is brought to bear against link 15so as to clamp the link between the head of the locking element and thehousing 22. This clamping action results from the engagement of cam 28with the 1 cam surface 29 on the housing. this cam action axiallydisplacing shaft 2% against the action of spring 31 to thus clanfp thelink 15 in the manner above described.

The wall of housing 22 is formed with a 15 slot 33'through which thehead of the loekini;

element may be withdrawn by axiallydisplacing shaft 24 against theaction of spring 3f..- Thus if the link 15 is so moved as to pohsitionithe slot 16 thereof parallel with slot 33 the two fastenermembers may be disconnect ed the enlargement 16" of the slot 16 permitwithdrawal of the head of the lockingeIement. With the fastening:members tlmsdisconnected the sashes can be opened a tetheiullextentprovided for by their constmction.

From the foregoing it will be immediately apparent that the abovedescribed window 1 Mien!!! not'only constitutes means forposi fivelylocking'the sash sections in completely elbsed ion but also providesmeans for l'ockiig the sash sections in adjusted positions. 1 It will beunderstood that in practice tllol'ink I5 will preferably be of alengtl'i which will permit of a relative adjustment of the sash sectionsto open position a distance insulficimt to permit the unauthorizedendream of a person through the window openso that irrespective of theclamping action: between the link and the complementary men section 26'entrance through the window opening could not be' gainedby raising orflowering either of the sash sections. How o'ler, the sash sections maybe raised or lowcred and secured in their adjusted position by theclamping engagement of head of the looking element upon link 15thereupon positively preventing any furtherrelative movement of the sashsections and also preventingany rattling of the sections. Bydisconnecting thQ fme! sections the sash sections may be opened asdesired. 7

'While the invention has been illustrated as q em ed in connection withsashes. it will fbt! obvious that it may be employed with equal facilityin connection with various other closures, as for instamce transoms andthe like. 7 A The construction of the several parts constituting myimproved window fastener is cult that they may be cheaply, quickly, anddumbly manufactured at a minimum cost and may be installed with facilitywithout 'ring the services of a skilled mechanic.

ile one specific embodiment of the invention has been illustrated anddescribed in some detail, it will be immediately apparent that variousmodifications in the specific structure illustrated may be resorted towithout departing from the spirit and scope of 70 this invention, and tothis end reservation is made to make such changes as may come within thepurview of the accompanying claims.
